Marketo Certified Expert Certification Practice Test

To prevent a Marketo form fillout from updating existing data in the Lead Source field, what should you do?

1. Create a user role to prevent it.

2. Create a custom layout in the field management area of admin.

3. Add a new custom field in the field management area of admin.

4. Block field updates in the field management area of admin.

The correct answer is: Block field updates in the field management area of admin.

The choice to block field updates in the field management area of admin directly addresses the concern of preventing the Lead Source field from being updated when a form is filled out. By blocking updates for that specific field, any submissions that would typically alter the Lead Source attribute will be ignored, ensuring that existing lead data remains intact. This is particularly important in maintaining accurate tracking of lead acquisition sources, which can impact reporting and overall marketing effectiveness. The other options may not adequately achieve the goal of preserving the integrity of the Lead Source data. For instance, creating a user role or a custom layout does not specifically tackle the issue of updating field data on form submission. Similarly, adding a new custom field might complicate data management without solving the specific necessity of restricting updates to the Lead Source. Therefore, blocking field updates is the most straightforward and effective approach in this scenario.
